Specification of Letters Patent. Patented Sept. 22, 1914.

Application filed January 2,1913. Serial No. 739,711.

bottle is in normal upright position, said stem having loosely connected thereto an in- I verted cup-shaped weight 20. The stem 19 H county of Middle passes through a central hole of the weight, sex and State of Massachusetts, have inventthe fit beingsuch as to permit of sliding ed certain new anduseful' Improvements in movementlongitudinally of the stem with N n-Refillable Bottles, ofwhich the follow- To a z lpwhom it may 5mm his invention has'for its object to proand weight is limited by suitable means, such as a glass stop ring or washer 22 cemented or fused to the stem, and-bearing looselyon the'weight. The inverted cup or weight 20 is formed with holes 23, 24 f he passage of liquid when the bottle is inverted as shown in Fig. 2.

When the bottle is in normal or upright position'as shown in'Fig. 1, liquid cannot be poured thereinto, because the valve 16, due not'only to its own weight and that of the I weight 20 but also to the weight of liquid .which would fill the cup 16, is seated so y upon the valve seat 15 as to prevent any liability of liquid entering the bottle. Theloose connection between the two cupshaped members permits the member20 to mg of a bottle is prevented." he invention consists in the improvements which I will now proceed to describe and claim. y I 'Of theaccompanying drawings, forming a part of this specificat1onz-Figure l represents a longitudinal section of a portionof the neck of a non-refillable bottle embodying some of the features of my invention, the neck'being in an uprightposition; Fig.2 represents a view similar to Fig. 1, showing the neck inverted and in position for pour- Fig. 3 representsa'section on line 33 of Fig. jl Fig. 4 represents the several movable membersof the device in side elevation, said members being separated from each the cupshaped weight, detached Fig. 6 is a view Fig. 1, but illustrating a different embodiment of my invention. 1 l i r The same reference characters indicate the figures. V rring first to Figs. 1 to 5 inclusive, 12 represents a bottle neck, and 13 a ring of g1 material, secured the. escape of liquid the moment that the bottl'eis tilted enough to begin pouring therefrom. When the bottle is nearly :emptied and is inverted to substantially such position I asshown in Fig, 2, the cup-shaped member ass, or other suitable within the neck at asuitable distance below the mouth thereof. Said ring has an upedge ofwhich is internally beveled to form a valveseat 15. The inner surface of the tubular extension 14 forms the outlet of the bottle. 16 representssa valve which is preferably cup-shaped, or concav'o-convex, its lower external surface. being formed tofit accurately the valve seat 15 andprevent access of liquid to the bottle when the valve is seated. 17 represents a guard, which is preferably a disk firmly secured to the interior of the bottle neck, above the valve seat, and spaced therefrom sufliciently to permit the opening of the valve, as indicated by Fig. 2.

he marginal portion of the guard 17 is provided with notches 18, forming liquidpassa es. The valve 16 has a stem 19 extending below the plane of'the ring 13 when the If the bottle isheld in an approximately vertical inverted position when air is exhausted therefrom, the liquid caused by the vacuum to flow upwardly toward the interior of the bottle will entrap air in the cavity of the now inverted slide in the central orifice in the Weight enoccupy such position as to readily permit ring which supports sometimes employed to the valve without overcoming the inertia of the weight, which under the described conditions remains in the position shown by Fig. 2. It will be seen therefore that although the weight is effective in holding the valve on its seat when the bottle is upright it does not act when the bottle is inverted,

the valve being closable by a vacuum 1n duced flow of liquid as easily as it would be if the weigh-twere not present.

Referring now to Fig. 6, which illustrates another embodiment of the invention, the the valve seat is shown at 131, said ring having a thin flange 14:1, the inner edge of which forms a valve seat 151 for the valve 16. The flange 141 is so thin that any such unusual external pressure as is refill bottles of other types would cause the cup-shaped valve 16 to hear so strongly against the valve seat as to break the said. seat so that the valve 16 and its loosely'connected weight 20 will im- 4 mediately pass to the bottom of the bottle,

made so thin be of a size to permit the cup-shaped valve enough so that cover 27 is to prevent fraudulent being placed so that the mere fact of the presence of these parts in the bottom of the bottle would indicate that the bottle did not still retain its original contents. The ring 131'is of course that its internal diameter will 16 to pass through the ring when the flange 141 is. broken. p

The valve 16 and its stem 19 are formed 1? with a small aperture or vent 26, the upper end of said vent aperture when the bottle is upright being closed by a vent cover 27 having a smallguiding stem 28 extending down through the vent 26, said stem 28 being small it does not completely fill the vent aperture, and being also long enough so that said guide stem will not slide entirely out of the vent aperture when the bottle is inverted. The object of the vent 26and its filling of the bottle by exhausting air therefrom when the bottle is in an upright position, liquid in the bottle neck above the valve. If the vent 26 and-its cover 27 were :not provided, the operation of exhausting air from the bottle neck above the valve, and through a cap temporarily applied t9 the neck, may under certain conditions tend to open the valve and'permit a relatively rapid flow of liquid contained in the upper portiopis ot this patent may be obtained tor The vent is of such small capacity that only to close the vent, so that; while the vent movement, the valve floated to its ture in its bottom,

tion of the neck into the bottle. The vent 26 and its cover 27 being provided,the with-5 5 drawal of air froni'the bottle neck will cause the escape of a limited quantityv of air from the interior of the bottle through the vent, so that the, valve itself will not be'opened. an inconsiderablequantity of liquid canpass through it into the bottle. Moreover, the cover 27, which is'of considerably" larger area than the vent, has a constant tendency serves the purpose of preventing the opening. of the valve int-he described operation, it 1 does not practically permit thefraudulent refilling of the bottle. j i

All of the parts described may befmadefof glass, although'I do not limitmysel f to con.- structing them of such material; e Having described my invention, I claim: 1. A non-refillable bottle" comprising" a ring secured in the neck f the bottle and forming a valve seat, a cup-shaped valve having its open end extending toward the mouth of the bottle,'the closed end of said valve being formed to close thevalve seat and having an inwardly projecting stem 8 provided with a stop, and a weightbelow the valve seat provided with a central orifice in which the said stem has a limited sliding being adapted to be 'seatwithout corresponding movement of the weight. 2. A non-refillable bottle comprisinga ring secured in the neck of the bottle and provided with an fopening forming a valve seat, a cup-shaped'valve having avent apeliand a vent cover located in said cup-shaped valve. 1 i 8. A non-refillable bottle comprising a ring secured in theneck ofthe-bottle and v provided with an opening forming a valve seat, acup-shaped valve having a vent aper- H ture in its bottom, and -a vent cover located in said cuP-shapedvalve, said vent cover having a guiding stem'in the vent aperture. In testimony whereof I have affixed my signature, in presenceoftwo witnesses.-
